Maintenance Interval
Maintenance Point
BLEEDING THE AIR. There may be times when the forks do
not rise while pumping when in the "LIFT" position. Most likely
this is because air has been introduced in to the hydraulic
system. The air can be removed by moving the control handle
to the "LOWER" position, then pumping the handle up and
down several times. Repeat this process until the forks lift as
intended.
SEAL AND O-RING REPLACEMENT FOR RAM AND
PLUNGER PISTON
Raise the pallet jack by pumping the handle.
Remove the spring pin (26). This will free the pump and
handle assembly from the pallet jack.
Remove the oil plug (58), turn pump over and empty the
oil into a suitable container. Pump the handle until all the
oil has drained. Dispose of the used hydraulic oil
according to local disposal regulations.
Pull out the plunger piston 64) and/or ram piston (60).
Remove all O-rings and seals. See Fig. 7.
Insert a new O-ring or seal one at a time making sure to
replace with the same size that was removed.
Reassemble and fill the oil tank through the oil plug hole to
80% capacity with new hydraulic jack oil, about 2-1/2”
deep in pump housing. See Fig. 6.

UP-DOWN CAM ADJUSTMENT
When pumping the handle with the lever in the neutral
position, there should be no movement of the fork. If there is
fork movement, the cam must be adjusted:
Place the lever in the neutral position.
Loosen the hex nut (19).
Adjust the socket head cap screw (20) while pumping
the handle, until there is no longer any movement of
the ram.
Tighten the hex nut (19).
